Original application filed September 11, 1911, Serial No. 648,635. Divided and this application filed March To all whom it may concern:

Be it known that I, Onnnm. ASHTON, a citizen of the United States, residing at Swampscott, in the county of'Essex and State of Massachusetts, have invented certain Improvements in Machines for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

' ,This invention relates to machines for use in the manufacture of boots and shoes and particularly to shoe shaping machines. The invention is herein shown as adapted for use-in connection with a machine of the type shown in British Patent No. 16,589/08, and this application is a division of appli-' cation Serial No. 648,635, filed Sept. 11,

I 1911. This type of machine comprises a rotary beater which includes a very rapidly ,rotated carrier or hub having annular end disks, between WhlCh d1sks extend stems or rods arranged around the periphery of the carrier and supporting an annular series of beating elements which strike a very rapid succession of light blows. The beating elements are arranged to be held out radially from the carrier by centrifugal force in noriiial operative position while the heater is rotating, and to yield inwardly when they strike the work. Machines of this type are employed with great success in pounding up the overlasted marginal portions of shoe upper at the sides of the bee] seat and, in some classes of work, along thcsides of the shank portions and forepar't of the shoe bottom.

The invention comprises the provision of new and improved work resting and guiding means especially adapted for use in a machine of the type aforesaid when, in' a common use thereof, it is desired to present the heel seat of a shoe to the beater for treatmentof one edge at a time. For sustaining one side of the heel=portion of the shoe during treatment by the beater of the heel seat at the other side, a horizontal member is I provided. This member forms a rest about wh ch the operator may rock the shoe longitudinally for'presenting it to the beater for treatment. In order to compensate for the lift of the shoe as it is thus turned about the rest,'the upper face of the rest is preferably curved so as to present a convexly rounded work resting surface. This provides that during the turning of the shoe the successive portions of the shoe presented to the beater will be in substantially the same horizontal plane and, therefore, in proper rela tion to the beater. Associated with the horizontal work resting member is a vertical abutment particularly. ad apted and arranged to prevent the beater from engaging and forcing outwardly toward the edge ,of the last bottom the upper on the lower side of the heel seat While the beater is forcing inwardly the upper .on the upper side of the heel seat.

Before a lasted shoe comes to the beater, the upper on the heel seat of the shoe has been permanently fastened by fully driven tacks. The portions of the overlasted upper along the shank-immediately in front of the heel seat are however held by tem porary partially driven side lasting tacks which must not be disturbed in the heel seat beating operation. Furthermore, if the beater were to engage this portion of the shoe upper it would knock out of shape the insole lip to which the upper is later to be secured by the welt attaching machine. It is therefore important that the port-ions of the upper held by the rear side lasting tacks should be protected from the action of the beater. Accordingly the vertical rest or guide is also arranged to protect the shank region of the shoe bottom from being engaged by the beater. To this end, the upright guide is provided with vertical lateral edges adapted. by engagement with the rear partially driven side lasting tacks to limit lengthwise movement of the shoe heelward and thus to restrict the action of the beater to the desired field .of operation;

Preferably, too, the upper corner portions of the vertical guiding and resting memher will each have a similar curvature to that of the upper face of the horizontal member so that, .as the operator turns the shoe, the lateral edge of the vertical guide will be in sliding contact with the rear side lasting tack, thus insuring that the vertical guide will all the time during the turning of the shoe protect those portions of the upper which are held by the side lasting tacks frombeing disturbed by the beater.,,,.,.}

In accordance with a further feature'of the invention the upper surface or edge of the upright supporting member; isprefic erably beveled so as to facilitate tipping the .shoe transversely of its longitudinal, axis for presenting the shoe to the beater at the desired angle and with the necessary pressure. a These and other features and advantages of the present invention, including certain details of construction and combinations of parts, will be fully set forth and explained in the following detailed description of so- 6. The end or stems 8 Which support much of a machine embodying a preferred form'of the invention as is necessary for a complete understanding thereof, and will then be clearly defined in the appended claims.

Referring to the drawings: Figure 1 is an angular perspective in elevation of so much of the machine as is concerned with the present invention; Fig. 2 is a plan view partly in section showing a heating element in operative relation to an edge of the heel seat J of a shoe; Fig. 3 is an end view in elevation,. showing in detail the operative rela-' tion between the beater, the shoe resting and guiding means and the work; Fig. 4c is a front view in elevation showing in detail the'relation of the shoe to the heater and the work resting and guiding means in the first position of the shoe; Fig. 5 isa view similar to Fig. 4, showing the last or eX- treme position of the shoe, with relation to the heater and the shoe resting and guiding means.

Bearings 2 on the frame of the machine support a shaft 4,- upon which is mounted a hub or carrier having end disks or flanges disks 6 are connected by rods an annular series of beating elements 10 confined] at their ends by collars12.

. As shown in Fig. 1, the above described beater may advantageously be employed in conjunction with a plate 14 which extends into close proximity to the outer-most position of the beating members, and is adapted to. engage the side of the shoe.- This plate 14 for resting the shoe cotiperates with the beating members-mshaping the side of the shoe at and adjacent to the edge'of the last extreme position by reason of the pressureof the'shoe against I it. The said plate may be stationary or, conveniently, to facilitate its cooperative action, it may be actuated by suitable means to beat or rub the upper.

For beating the sides and the bottom of the heel portion of-the shoe and also the sides of the forepart'of the shoe bottom, the shoe may be rested on a horizontal member 1G, as illustrated in Figs. 4 and In the common use of the machine for heel seat beatln the said member 16 will thus serve as a rest for one side ofthe heel portion 5107f; tires-shoe at a time for presenting the shoe to the beater for treatment of the heel t atthe other side, as clearly shown in 3.] Preferably, and as shown, the upfface of the member 16 is convexly rduifi'detl to facilitate turning the shoe from the" first position shown in Fig. 4: to the sure-that during'this turning the successive portions presented to the beater will be in the sanie horizontal plane, thus compensating for the lift of the' shoe;

.The 'member lG 'hjs associated with it a vertical abutment'or guide which consists of a relatively thin-plate 18, having a horizontal-extension 20 supported upon a flat part 22, fixed to an upright post 24 which machine frame by a set screw. The horizontal rest 16 caps the extension 20 of the vertical gulde 18 and a set screw- 23 passing through a hole in the part 22 and through shown in Fig. 5, and to inis adjus'tably secured in a bracketon the a somewhat elongated transverse slot 27 n the extension 20, has-screw threaded engagement with the rest 16, thereby binding By reason of the the said parts together. elongated transverse slot in the extension 20, the vertical guide 18 can, if desired,'be adjusted toward or from the beater.

The end portions of the guide 18 form at 4 each lateral side of the restlG vertical stops 26 which are intended and arranged, as shown in Figs. 4 and 5, to engage the heel side of the rear partially driven side lastin tack 25 on the side of the shoe supporte by the rest 16. These stops during the action of the beater upon the heel seat at the other side, serve to restrict lengthwise movement of the shoe heelward, limiting the-field of actionof the beater so as to prevent engagement of the beater with the portion of 'overlasted upper held by the side lasting tacks. The member 18 also constitutes a guard to prevent the beater from engaging and forcing toward the edge of the last bottom the upperon the lower sideof the heel seat while the heater is forcing inwardly the upper on the upper side of the heel seat. Moreover, if it is desired to treat the shank region of the shoe, the vertical member inthe last or extreme stead of engaging a rear side lasting tack may be interposed between the beater and the side lasting tacks on the lower side of the' shank, and by such interposition pretent these tacks from being disturbed during treatment of the shank athe upper side.

Preferably, the'upper corner portions of the vertical rest 18 are rounded similarly (Fig. 1) to the upper face of the member 16. As a result, for manipulating the shoe from the first position shown in Fig. 4 to 7 position showntin Fig. 5, the shoe may be rocked about the rest 1 without disturbing the guiding engagement of the member l8owith the rear side lasting tack 25 which will slide along the edge of the'member 18 as the shoe is turned.

In order to facilitate tipping the shoe transversely of its longitudinal axis, causing the side of the heel seat to be treated to bear against the beater with the'required pressure and at the desired angle, theupper. and end edge port-ions of the vertical member 18 ma be beveled as illustrated in Fig. 1.

lthough, for convenience, the above described work resting and guiding means are herein shown in connection with the machine shown and described in applicants copending application Serial No. 648,635, of which as above stated this application is a divisiol n the said' machine parse is notclaimed" herein, the novel features thereof being claimed in the said co-pending application.
